Product Overview
The Ethos 30.7 kWh Stackable Battery System combines six Ethos 51.2 V / 100 Ah LiFePO₄ modules in parallel, offering a robust and scalable solution for demanding energy needs. Its modular design provides exceptional flexibility — you can start small and expand later as your system grows.
Each Ethos module includes its own smart Battery Management System (BMS) to ensure real-time monitoring, cell balancing, and protection against over-voltage, over-current, and temperature extremes. When stacked, the included Ethos Control Box manages communication between modules and your inverter, providing a clean plug-and-play installation experience.
With over 95 % round-trip efficiency and a cycle life of up to 8,000 cycles at 80 % depth of discharge, the Ethos 30.7 kWh delivers exceptional long-term performance. Its IP65 enclosure ensures protection from dust and moisture, allowing for flexible mounting in protected outdoor or indoor environments.
Designed for energy independence, this high-capacity stack supports residential microgrids, off-grid cabins, small businesses, and large solar arrays. The Ethos line is also certified to major international safety standards, ensuring reliability and compliance.
